About this study

Pulmonary embolism (PE) is a life-threatening condition and a leading cause of cardiovascular mortality. While systemic thrombolysis is the standard treatment for high-risk PE, its bleeding risk limits use in some patients, highlighting the need for alternative reperfusion strategies such as catheter-directed thrombolysis (CDT). This prospective study will evaluate the safety and efficacy of CDT using the EkoSonic Endovascular System (EKOS; Boston Scientific) in patients with intermediate-high and high-risk PE. The primary outcome is all-cause mortality through 360 days of follow-up, with secondary outcomes including changes in echocardiographic parameters such as the RV/LV diameter ratio.
